Listing 7-2. To use this method call: ClassNameHere.infoBox("YOUR INFORMATION HERE", "TITLE BAR MESSAGE"); or ClassNameHere.infoBox("YOUR INFORMATION HERE", "TITLE BAR MESSAGE", "HEADER MESSAGE"); share|improve this answer edited Apr 11 at 7:41 answered Sep 21 Other methods you're likely to call are defined by the Dialog, Window and Component classes and include pack, setSize, and setVisible.

Listing 7-18. You can do this with a try catch block. In this case, you must implement your own property change listener so that when the user clicks a button, the dialog does not automatically close. Assertions are statements that can print to indicate that a particular piece of code is not behaving as expected.

Table 7-3. The ProgressMonitor class can put up a dialog that shows the progress of an operation. A complete example Now looking at this as a more complete showMessageDialog example, here is the source code for a complete Java class that demonstrates a showMessageDialog example with a slightly Complaints?

The program will run but, because you did something wrong with the coding, there's a good chance the entire thing will crash. final JOptionPane optionPane = new JOptionPane( "The only way to close this dialog is by\n" + "pressing one of the following buttons.\n" + "Do you understand?", JOptionPane.QUESTION_MESSAGE, JOptionPane.YES_NO_OPTION); final JDialog dialog JOptionPane's icon support lets you easily specify which icon the dialog displays. Take note of the syntax that is being used for defining the variable that holds the exception.

To specify that the dialog display a standard icon or no icon, specify the message type corresponding to the icon you desire. For instance, the StopIteration exception is raised by a program to stop the iteration of a loop…not to flag an error with the program.

This would be a case when you’d like to raise your own exception. To create a custom dialog, use the JDialog class directly. Can also be used to specify icons to be displayed by the buttons or non-button components to be added to the button row. Listing 7-1.

Problems with the examples? This will give you an opportunity to compare the two syntaxes and appreciate the flexibility that Python offers. Object initialValue Specifies the default value to be selected. However, if you’d like to control the type of warning that is issued, you can also pass the warning class.

Replacing a pattern with a string When is it okay to exceed the absolute maximum rating on a part? Component parentComponent The first argument to each showXxxDialog method is always the parent component, which must be a Frame, a component inside a Frame, or null. A Dialog can be modal. registry represents all of the current warning filters that are active.

Python offers a couple of different options if you need to do such exception handling. The specific warning is matched against each filter specification in the list in turn until a match is found. All rights reserved. If you're going to use JDialog directly, then you should understand the material in Using Top-Level Containers and How to Make Frames, especially Responding to Window-Closing Events.

This works with object that extends the context management protocol. A fourth method, showInputDialog, is designed to display a modal dialog that gets a string from the user, using either a text field, an uneditable combo box or a list. Creating a Simple Object That Follows Context Management Protocol # In this example, my_object facilitates the context management protocol # as it defines an __enter__ and __exit__ method class my_object: def Python with Statement Example # Read from a text file named players.txt >>> from __future__ import with_statement >>> with open('players.txt','r') as file: ... x = file.read() ... >>> print

You can also perform many other kinds of customization. //Custom button text Object[] options = {"Yes, please", "No, thanks", "No eggs, no ham!"}; int n = JOptionPane.showOptionDialog(frame, "Would you like some Table 7-1 lists the exceptions defined in the Python language, and the indentation resembles the class hierarchy. It happens more often than it should because most exceptions can be caught and handled nicely. raise MyNewError("Something happened in my program") A more involved exception class may be written as follows.

Listing 7-14. Python has similar constructs to that of Java, and we’ll discuss them in this chapter. posted 9 years ago Yes, you need the request/response objects to redirect to another page.

See The New Modality API for details. A modal dialog will appear. Though this dialog is rather useless as written, its code is simple enough that you can use it as a template for more complex dialogs. Default the message-box title to the name of the calling method. For example, here is an informational dialog: Here is the code that creates and shows it: JOptionPane.showMessageDialog(frame, "Eggs are not supposed to be green."); The rest of this section covers the You can use a custom i...
